geschmalzenen the price, the Olympus calls for their Geli is the JJC Lens Hood fine. Sure, compared to the ingenious and especially very low-aluminum bezel for 46mm threaded (20mm and 14mm Panasonic Pancakes) sees this plastic part very modest, but it does the job. Positive is definitely the price and that they can be mounted upside down to save space attached. Negative contrast is the plastic thread that does not neatly completes and always somehow loosely acts. Because it is plastic, it can also rotate about what the long term can certainly not be healthy for the delicate thread. Quite I do not understand how JJC rausbringt such a high quality milled aluminum cover with 46mm thread for under 10 and thus produces a savings option combined with a higher price in the 37mm. While there is an aluminum cover from JJC for 37mm thread, which is much too shallow to be of service to be on the Olympus 45mm.
